Avengers preferences

I figured I should probably tell you what I am going to do, here in this book. For part ones, it will include Bruce, Bucky, Clint, And Loki. Part twos will be Sam, Steve,Tony, and Thor.
LS in the title means that they would be your big brother in that one.
Daddy just means that they are your father in that preference.
I won't be writing smut, just nice fluff and things to satisfy fan girl needs.
Also Y/N means your name..... Pretty sure other abbreviations won't be that hard to figure out. So here goes!!!
